T 0 all whom it may concern:

, Be it known that I, Ax'rnoNrVoms, a citizen of the United States, and a resident of the city of New York, borough of Man hattan,.in the county and State of New York, have invented a newand Improved Photographic Camera, of which the followinglis a, full, clear, and exact description.

. yinvention relates to new and useful improvements in photographic cameras, and relates more particularly to that style of camera in which the image formed by the lens is focused upon a screen at the-front of the plate-holder and is observed by the openter through a suitably located aperture in the camera box.

An object of my invention is to provide a device whereby at the time of taking the picture, the image is automatically focused on the sensitized plate, said screen having an opening atits upper part, the lower part of said screen being opaque 'to shut out light from the plate, the aperture through which the image is viewed is closed to shut out extraneous light andthe focusing screen caused to rush across the plate, said screen having an opening at its upper part and then an opaque part to shut out light from the plate, thisbeing effected instantaneously.

With the above and other objects in view, as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts hereinafter fully described, illustrated the accompanying drawings, and more particularly pointed out in the appended Reference is to be had to the accompanying drawings, forming a part ofv this speci-- fication,'in'which imilar characters of reference'indicate corresponding parts in all the figures, and in which- Figure 1 is a vertical longitudinal view taken through a preferredembodiment of my invention, showing the bellows in extended position; Fig. 2 is a view similar to Fig. 1, showing the bellows in collapsed position and the camera closed; and Fig-3 is a side view of part of the camera, with a portion of the side broken away to show the internal mechanism positioned within a side compartment.

In the several figures is shown a plate camera having a box or casing A provided with a forward 0 enin (1 adapted to be closed, by a hinged ed and within which fitsa frame, C. A bellows D extends from this frame C to. the camera front E, as is customary with cameras of this general character. The front E is a'djustably mou nted upon the rack e, which rack is mounted .on the bed B and is actuated through the operation of a knob e to focus the camera. 4 Rigidly mounted in the camera front E,

is a cylindrical thimble 4, rotatably mounted I by one'end'of a tension spring 9, the opposite and upper end of which is attached to a pin 10 pro ecting inwardly from the front E. By this "construction, the lens 6 is normally maintained in its advanced position, and the length of the horizontal projection of theslot 8 is equal to the distance between the focusing screen and the plate hereinafter described. A stop ring 11, forming an abutment for the' lens-carrying "sleeve 5 against the front E, has a 'pin 12 projecting therefrom, to which pin is attached a flexible connection 13, the opposite end of which is disposed about a spring roller 14 mounted within the casing A. By thisconstruction, it will be understood that drawing the flexible member 13, will rotate the lens-carrying sleeve 5, which'rotation will cause the lens to move toward the sensitive plate a distance equal to the distance between the focusing.

screen and the sensitive plate. The focusing screen 15 is disposed immediately in front of the exposed opening 16 in the rear of the casing A and in optical alinement with the lens 6, and has itscopposite ends disposed onspring drums 17' and 18 journaled in the casing A below and above the opening. The screen 15 is white on the side facing the lens and upon said screen is adapted to be formed the picture image. Within the screen is an aperture, not shown, which maybe caused to speed across the opening front of the pjlate, when it is desired to bring the image on the sensitive plate 191, the exposure being terminated by the up or art of the curtain which again closes t e:l1ght opening 16. The amount of light may be varied by causing the curtain to travel across the late at any suitable speed which is obta ned by altering the spring tension drum ll', or site of the aperture curtain l5 be chenged In order to ViEW fo nod on screen 15, the top of the casing opening 19 therein, and the top of the frame has on opening 222 which openings are normolly closed hy ntrdp door 20 hiiigedto its front edge, said door n w maintained in oi the door 20. From the mirror 22, the im- 7 age is reflected to a second mirror mounttill ed onetrsp door 26, the upper edge of which is pivoted at 27 to the forward under edge of the door 20,- undthe mirror 25. is eds ted to fit within; a, recess 28 in the under si 'e of the door 20 when the door is in the folded position shhwn more particularly in Fig. 2.
